When primary monitor is smaller than the actual monitor on which the window is being maximized, the WM will do widnow size adjustments that will completely screw the window size if we try to make it smaller than 100% fullscreen (to account for taskbar size, for example). Fix this by overriding maximized window size during WM_WINDOWPOSCHANGING. https://bugzilla.gnome.org/show_bug.cgi?id=775808
